PF-2 Fluoride and Arsenic Reduction Filters (Set of 4)
The PF-2 reduction elements screw onto the bottom of the Black Berkey water purification elements and work in conjunction to adsorb the following unwanted elements found in drinking water.
• Arsenic V and pre-oxidized Arsenic III
• Other residual heavy metal ions
FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (>95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).
ARSENIC: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.
REPLACEMENT: Under normal circumstances, a set of 2 fluoride filters should be replaced every 1000 gallons

I could tell it was time to put in my new fluoride filters when my water taste changed. So much better now. I did find I has an oil film with this batch but after some research it just needed to filter more. This was a pain for a bit.

These filters are great! They filter out so much. We are very happy with our Berkey. Great tasting water.

We couldn't be happier with our Berkey. The water tastes so good and we wouldn't want to be without it. Thank you.

The water tastes great! We use it for almost everything. We fill bottles with our Berkey water so when we leave our house the kids have the best and won't consume the harsh chemicals and fluoride that's in most city water.

I purchased a Royal Berkey last year. My city adds sodium fluoride to the water. I have 4 first stage filters and 4 fluoride filters installed in my Berkey. The water that comes out of the spigot is THE BEST WATER I have drank. I had been using bottled water to avoid the fluoride and other chemicals. The Royal Berkey paid for itself in less that eight months!

These filters do a great job of filtering out fluoride from your water! Remember to screw them on with eight turns.
